[Terrapreta] Using wasted energy from ICE exhaust to produce charcoal

[Duane Pendergast]

Dear Colleagues,

I've idly wondered about using the waste heat from the exhaust gases of an
ICE to produce charcoal. This could be a basis to develop a system to
convert agricultural wastes to charcoal on the spot. Some Google searching
revealed a single paper. The abstract is below. Has anyone encountered more
information on this?

Abstract


A rural area power supply system (RAPSS) which produces charcoal as a
by-product for use elsewhere through the gasification of biomass fuels is
modelled. The power generation system utilizes a conventionally-fuelled
engine-generator combination to produce electricity for local use. The
energy needed for the gasification process is obtained from the exhaust
gases from an internal combustion (IC) engine, which could be a petrol
engine, a diesel engine or a gas engine. In this particular model, a diesel
engine-generator system is specifically used. The charcoal production system
being modelled is a small-scale system, producing between 20 and 60 kg of
charcoal per hour, with the diesel engine running at its rated capacity. The
special features and constraints which govern such a system operating in a
rural environment of a developing country are addressed, followed by a study
of the rate of charcoal production from a given system, using thermodynamic
relationships. The key features of such a system include reliability,
simplicity of operation, robustness, operation by local personnel and a
level of technology appropriate to the location of the system.
